Functions ¶
Types ¶
type ControlField ¶
type ControlField struct {
Tag string `xml:"tag,attr"` // 3 chars
Value string `xml:",chardata"` // if Tag == "000"; 40 chars
}
ControlField represents a control field in a MARC record.
type DataField ¶
type DataField struct {
Tag string `xml:"tag,attr"` // 3 chars
Ind1 string `xml:"ind1,attr"` // 1 char
Ind2 string `xml:"ind2,attr"` // 1 char
SubFields []SubField `xml:"subfield"`
}
DataField represents a data field in a MARC record.
type Decoder ¶
type Decoder struct {
// contains filtered or unexported fields
}
Decoder can decode MARC records from a stream.
func NewDecoder ¶
NewDecoder returns a new Decoder for the given reader.
type Record ¶
type Record struct {
XMLName xml.Name `xml:"record"`
Leader string `xml:"leader"` // 24 chars
ControlFields []ControlField `xml:"controlfield"`
DataFields []DataField `xml:"datafield"`
}
Record represents a MARC record.
func MustParse ¶
MustParse parses the give MARCXML-encoded data and records a Record, but panics on errors.
func MustParseString ¶
MustParseString is like MustParse, except it accepts a string instead.
func (Record) ControlFieldAt ¶
func (r Record) ControlFieldAt(tag string) (ControlField, bool)
ControlFieldAt returns the control field of the given tag, along with a boolean denoting if it was found or not.
func (Record) DataFieldAt ¶
DataFieldAt returns the first occurrence of DataField with the given tag, along with a boolean denoting if it was found or not.
func (Record) DataFieldsAt ¶
DataFieldsAt returns all occurrences of DataFields with the given tags.
type Relator ¶
type Relator struct {
// contains filtered or unexported fields
}
Relator is a known Marc relator, associated with a 3-letter code. The codes are maintained by Library of Congress. TODO drop struct; type Relator string suffices
func ParseRelator ¶
ParseRelator parses the given string and returns a Relator if it matches a known 3-letter Marc Relator code.
